searchInLocalRepo: Search for an Artifact in a Repository Using `Tags`

Description

searchInRepo searches for an artifact in a Repository using it's Tags. To learn more about artifacts visit archivist-package.

Usage

searchInLocalRepo(pattern, repoDir, fixed = TRUE, realDBname = TRUE)
searchInGithubRepo(pattern, repo, user, branch = "master", fixed = TRUE)

Arguments

pattern

If fixed = TRUE: a character denoting a Tags to be searched for in the Repository. It is also possible to specify pattern as a list of length 2 with dataFrom and dataTo;

repoDir

A character denoting an existing directory in which artifacts will be searched.

repo

Only if working with a Github repository. A character containing a name of a Github repository on which the Repository is archived.

user

Only if working with a Github repository. A character containing a name of a Github user on whose account the repo is created.

branch

Only if working with a Github repository. A character containing a name of Github repository's branch in which Repository is archived. Default branch is master.

fixed

A logical value specifying how artifacts should be searched for. If fixed = TRUE (default) then artifacts are searched exactly to the corresponding pattern parameter. If fixed = FALSE then artifacts are

realDBname

A logical value. Should not be changed by user. It is a technical parameter.

Value

searchInRepo returns a md5hash character, which is a hash assigned to the artifact when saving it to the Repository by using the saveToRepo function. If the artifact is not in the Repository a logical value FALSE is returned.

Details

searchInRepo searches for an artifact in a Repository using it's Tag (e.g., name, class or archiving date). Tags are submitted in a pattern argument. For various artifact classes different Tags can be searched for. See Tags. If a pattern is a list of length 2, md5hashes of all artifacts created from date dateFrom to data dateTo are returned. The date should be formatted according to the YYYY-MM-DD format, e.g., "2014-07-31".

Tags, submitted in a pattern argument, should be given according to the format: "TagType:TagTypeValue" - see examples.
